March 10 (Reuters) - The S&P 500 rose on Wednesday and the blue-chip Dow hit a record high after tepid consumer price data for February calmed inflation worries and Congress gave final approval to one of the largest economic stimulus measures in U.S. history.
A rotation into sectors such as energy and financials continued, both in small- and large-cap stocks, as investors bet on consumer spending when the U.S. economy reopens and sold the big tech names that have fueled the rally since last March.
An expected economic surge once the coronavirus vaccines are rolled out along with the monster fiscal stimulus have triggered inflation fears and a spike in Treasury yields, leading the Nasdaq to tumble as much as 12% from its Feb. 12 record close.
But an auction of $38 billion in benchmark 10-year Treasury notes was not as bad as feared as underlying inflation remained muted, helping push yields down to a session low of 1.506%. "market seemed nonplussed and Treasuries rallied but that didn't seem to give a boost to tech (stocks)," said Mark Luschini, chief investment strategist at Janney Montgomery Scott.
Rising yields have weighed on technology shares as they rely on cheap funding for growth.
Investors are shifting funds from tech stocks with lofty valuations to other groups, such as energy and financials, that are undervalued and more of a play on an improving economy in a post-COVID world than big tech is, said Peter Tuz, president of Chase Investment Counsel in Charlottesville, Virginia.
"It is occurring in fits and starts," Tuz said. "That is essentially the overwhelming theme in the market right now and it probably will continue until these things run their course."
The move away from Apple Inc AAPL.O , Amazon.com Inc AMZN.O , Facebook Inc FB.O , Tesla Inc TSLA.O and Microsoft Corp (NASDAQ:MSFT) MFST.O , all down on the day, led small-cap stocks .SPCY to rise more than double the gains of the S&P 500.
Also helping lift equities are rising estimates for U.S. corporate profitability this year following surprisingly strong fourth-quarter earnings and growing optimism about the recovery. the Dow Jones Industrial Average .DJI rose 1.45% to end at 32,295.71 points, while the S&P 500 .SPX gained 0.60% to 3,898.73.
The Nasdaq Composite .IXIC dropped 0.04% to 13,068.83.
